Hello.Are you referring shingles to chicken pox
or herpes zoster
.Most of the times Herpes zoster(in lay man's terms shingles) is a one time episode, unless you are severely immunocompromised. Vaccine has no role in causing or preventing shingles. The rash that you have may be totally different-check with your dermatologist
for a complete solution.A skin biopsy
may be required to confirm.
